What's Going on With the Volcano?

October 1, 2014

 
The eruption of Kīlauea volcano continues at two locations. In the park, the vent within Halema'uma'u Crater is easily viewed from the overlook at the Jaggar Museum. The second location is the Pu'u 'Ō'ō vent located 10 miles (16km) east of the summit, on the remote east rift zone of Kīlauea. This area is not accessible to the public, (see "East Rift Zone Vents" below). Lava is no longer flowing into or towards the ocean.

Fumes and glow from the lava lake within the vent at the summit of Kīlauea may be seen from the Jaggar Museum overlook and other vantage points along Crater Rim Drive.

During the day a robust plume of volcanic gas is a constant and dramatic reminder of the molten rock churning in a lava lake within the crater. After sunset, Halema'uma'u continues to thrill visitors and park staff with a vivid glow that illuminates the clouds and plume (weather permitting).

Park rangers are on duty at the Jaggar Museum to assist the many visitors drawn to the site which has been erupting within the crater since March 2008.

HOT LINES for Eruption Information

The June 27th lava flows from Pu'u 'Ō'ō are outside the park and the flow front is presently more than 10 miles east of Hawaii Volcanoes National Park's eastern boundary. The flows are inaccessible by foot or by car and the area is closed to the public.

October 1, 2014 - The June 27th lava flow remains active. Based on observations from HVO webcams, there have been no significant changes to the flow front since yesterday. On Monday breakouts of lava were observed where the flow first enters the crack system about 8 km (5 mi) behind the stalled front, and where it exits the crack system about 3 km (2 mi) back from the front. At the leading edge of the flow, two lobes of weak surface activity were observed at 125 m (410 ft) and 580 m (1900 ft) behind the front. Both lobes were creeping northeast around the north side of the existing flow. An HVO overflight is scheduled this morning.

East rift zone: This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone in relation to lower Puna. The area of the flow on September 26, 2014, at 11:15 AM is shown in pink, while widening and advancement of the flow as mapped on September 29 at 10:30 AM is shown in red. The distal tip of the flow was inactive, but small breakouts were scattered across the surface of the flow upslope from the stalled front. The closest surface activity to Pāhoa was about 125 m (137 yards) behind the stalled front. Several breakouts were also active midway along the length of the flow near where lava first entered the crack system.

The blue lines show down-slope paths calculated from a 1983 digital elevation model (DEM). For an explanation of down-slope path calculations, see: http://pubs.usgs.gov/of/2007/1264/. Down-slope path analysis is based on the assumption that the DEM perfectly represents the earth's surface. DEMs, however, are not perfect, so the blue lines on this map indicate approximate flow path directions. All older Puʻu ʻŌʻō lava flows (1983–2014) are shown in gray;the yellow line marks the lava tube.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates. Small breakouts were scattered across the surface of the flow upslope from the stalled front. Several breakouts were also active midway along the length of the flow near where lava first entered the crack system.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of the June 27th lava flow. Surface activity near the flow front was advancing slowly northeast in two lobes. The lobe farthest from the vent (the closest to Pāhoa) was about 125 m (137 yards) behind the stalled flow front. It traveled about 80 m (87 yards) since Friday, September 26. A second lobe was about 580 m (634 yards) back from the stalled front, and it moved only about 65 m (71 yards) since Friday.

Did You Know?

`iliahi is the Hawaiian name for sandalwood.

During the 1800's, vast quantities of fragrant sandalwood were the first major export of the Hawaiian Islands. The trade nearly caused the extinction of `iliahi or sandalwood (Santalum paniculatum).
